摘要
基于合成孔径雷达(SAR)发射脉冲信号的脉间相参性,该文提出通过测量分析SAR方位向线性调频信号特征的方法,获取目标SAR的距离等信息.与常规TOA观测相比.这种方法用相位度量代替时间度量,避免了常规TOA观测对测时精度要求过高的困难。
Based on the phase correlativity between pluses of Synthetic Aperture Radar (SAR), a new observation method is presented. By the method the SAR's location information can be obtained from the characteristics of the observed azimuth chirp signals of SAR. Compared with the normal TOA observation, the method that uses a phase measurement instead of time measurement, could avoid a severe demand of time measurement accuracy.
